Notice of List of Explosive Materials.


This notice publishes the 2019 List of Explosive Materials, as required by law. The 2019 list is the same as the 2018 list published by ATF, except that the 2019 list adds four explosives not previously listed.


The list becomes effective January 2, 2020.

Pursuant to 18 U.S.C. 841(d) and 27 CFR 555.23, the Department of Justice must publish and revise at least annually in the Federal Register a list of explosives determined to be within the coverage of 18 U.S.C. 841 et seq. The list covers not only explosives, but also blasting agents and detonators, all of which are defined as “explosive materials” in 18 U.S.C. 841(c).

Each material listed, as well as all mixtures containing any of these materials, constitute “explosive materials” under 18 U.S.C. 841(c). Materials constituting blasting agents are marked by an asterisk. Explosive materials are listed alphabetically, and, where applicable, followed by their common names, chemical names, and/or synonyms in brackets. This list supersedes the List of Explosive Materials dated December 12, 2018 (Docket No. 2018R-03, 83 FR 63906).

The 2019 List of Explosive Materials is a comprehensive list, but is not all-inclusive. The definition of “explosive materials” includes “[e]xplosives, blasting agents, water gels and detonators. Explosive materials, include, but are not limited to, all items in the `List of Explosive Materials' provided for in § 555.23.” 27 CFR 555.11. Accordingly, the fact that an explosive material is not on the annual list does not mean that it is not within coverage of the law if it otherwise meets the statutory definition of “explosives” in 18 U.S.C. 841. Subject to limited exceptions in 18 U.S.C. 845 and 27 CFR 555.141, only Federal explosives licensees and permitees may possess and use explosive materials, including those on the annual list.

Pursuant to its obligation to revise the list of explosives determined to be within the coverage of chapter 40 as set forth in 18 U.S.C. 841(d), the Department is adding four explosives to the 2019 List of Explosive Materials. The four explosives being added to the 2019 list, in alphabetical order, are: (1) “dipicryl sulfide” and its synonym “hexanitrodiphenyl sulfide”; (2) “nitrotriazolone” and its synonym “3-nitro-1,2,4-triazol-5-one”; (3) “trinitrobenzenesulfonic acid” and its synonym “picryl sulfonic acid”; and (4) “trinitrofluorenone.” None of these four explosives previously appeared on the list under other names.

The Explosives Research and Development Division (ERDD) at ATF's National Center for Explosives Training and Research (NCETR) performs research and analysis on materials that may be characterized as explosives materials. Upon a comprehensive review of literature on the relevant material and comprehensive research to determine if the material is synonymous or has structural correspondence with other listed explosives, including review of the Department of Transportation's Hazardous Materials Table, the National Oceanic and Atmospheric Administration's CAMEO database, and other explosives community accepted materials, ATF determined that each of these substances is an explosive under 18 U.S.C. 841(d). The addition of these four explosives to ATF's annual list codifies ATF's determination that these are explosive materials regulated under 27 CFR part 555.

Furthermore, the addition of these four explosives to the annual list of explosive materials creates interagency consistency with the classification of these materials as regulated materials by ATF, the Department of Homeland Security (DHS), and the Department of Transportation (DOT). All of these substances are listed on DHS's Chemical Facility Antiterrorism Standards (CFATS) Appendix A: Chemicals of Interest (COI) List, see 6 CFR part 27 Appendix A; and DOT's Hazardous Materials Table, see 49 CFR 172.101. Therefore, for purposes of clarity and consistency, ATF is adding these explosives to the annual list.

As stated, the annual list of explosive materials is a comprehensive list, but is not all-inclusive. Businesses or others subject to the federal explosives Start Printed Page 129regulations at 27 CFR part 555 should not be impacted by the addition of these explosive materials to the annual list because all explosive materials, including those not on the annual list (with the exception of certain materials noted in exemptions at 18 U.S.C. 845 and the implementing regulations at 27 CFR 555.141), already are regulated under this part. These materials are subject to the restrictions and regulations in this part regarding the requirements for manufacture, storage, distribution, use, and licensing or permitting. Any person who receives explosive materials is already required to be licensed as an importer, manufacturer, or dealer in explosive materials, or to hold a permit as an explosives user. For persons who already hold a license or permit under the explosives laws, no further action on their part would be required for them to acquire newly-added explosive materials.
